Direct Messages not working

Wife told me she sent me a TikTok, but it wasn’t there.

I asked if she saw the last couple I sent her today, and she hadn’t.

We’re sitting next to each other trying to send messages and they just aren’t sending. We can even see the typing indicator on each other’s screens, but then the sent message just isn’t displayed.

Killed the app on both phones, signed out, signed in, etc. Not sure what’s going on but wondering if it’s a widespread issue?
